I'm trying to get Xinerama working on my laptop, one display being the LCD panel and then a CRT monitor. The LCD powers up and works when X starts, but the CRT remains in a standby state. There is a CRT/LCD keyboard switch, which will turn off one and turn on the other, but that's really not what I want. Perhaps someone can help me out? /etc/X11/XF86Config follows. I have an Intel 852GM (Centrino) video chipset. My distro thingy says FC2, but for another reason I'm temporarily running FC1. TIA.

Oh, yeah. And this, for whatever its worth:

[abarr@localhost abarr]$ cat /var/log/XFree86.0.log | grep Xinerama
(**) Option "Xinerama" "on"
(**) Xinerama: enabled
(WW) I810(0): Direct rendering is not supported when Xinerama is enabled

Here's the config file:

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
